Creating identical haunches from beam profiles

By default, if a beam is named "HAUNCH" and cut accordingly, the Single-Part Drawing of that beam will try to double the haunch, so that two haunches can be manufactured from a single beam.

This functionality can be controlled with the advanced setting XS_DRAWING_USE_WORKSHOP_FORM_FOR_DOUBLE_PARTS_IN_SINGLE_PART_DRAWINGS.
For more information, see this article.

However, in order to get two identical haunches from a single beam, the haunch must be modelled in a specific way. The beam will be cut diagonally in half by using a Line cut. Line cuts will be drawn as lines in the drawing, which indicate the cutting line. If the ends need to be trimmed at an angle, use Fit part end. Fittings will not be drawn in the Single-Part Drawing as lines. Be sure to trim both ends of the beam at the same angle (more on this below).

If the ends are trimmed with line cuts, or at a different angle to each other, the result will not be as desired. Below is a comparison of drawings of haunches. Only the leftmost drawing produces two identical haunches.

In the middle drawing the lower right corner is faulty. It is also missing a cut line at the right side which would be required to make the haunches identical. The rightmost drawing has a completely flat end, so the haunches will be different.
